Filters

Filters are essential in research laboratories and many other industries for removing particulates and creating environments conducive to a wide array of experiments and procedures. The devices come in different forms including in-line filters, paper discs, small capsules, and large ventilation panels. Filters also purify and concentrate the liquids and gases required for testing. For air, this means removing pollution, moisture, and solid airborne particulates; for liquids, this means removing impurities and small contaminants.
